Phyllida Lloyd, a theater veteran who helmed the original London staging, is in talks to make her feature directing debut.

"Mamma Mia!" focuses on a bride-to-be who invites three men who might be her father to her wedding. Hilarity ensues along with some 22 ABBA classics including such usual suspects as "Dancing Queen" and "Take a Chance on Me."

The incomparable Meryl Streep will star as the bride's mother. It will be her first on-screen musical proper, although she's showed off her pipes in "A Prairie Home Companion," "Postcards Form the Edge" and "Death Becomes Her."
